finished the game! It's pretty fun maneuvering inside the dark areas, and with the dash gives me a sense of freedom in the movement. though there's some visual glitches (like the player sprite not changing after I'm done clinging to a wall) and a difficulty in wall jumping (which could be polished a bit more), I really love the level design, especially the part where there's a hidden lumen, like how there was a subtle hints by how the platforms and the dark zones are positioned.
